If you have solar PV panels, or are planning to install them, then using home batteries to store electricity you’ve generated will help you to maximise the amount of renewable energy you use. In fact, 60% of people who have, or would consider, a home battery told us the reason was so they could use more of the electricity generated by their solar panels.* Home-energy storage will also reduce the electricity you use from the grid, and cut your bill. If your home is off-grid, it can help to reduce your use of fossil fuel back-up generators. In the near future, time-of-use tariffs will let you store up electricity while it’s cheap (overnight, for example) so you can use it during peak times. A few energy companies have launched these already.
